Haha! That was actually pretty cool, shows that the guy has some personality at least!
I really hated seeing people chastising Big E after he barely said 3 sentences on Raw on Monday. Judging the guy based on that is ridiculous if you ask me. Based off video there though, he seems to have some charisma at least. We'll have to wait for him to have some more mic time though before making a fair judgment.
As for the stutter, Main Event is taped, so they could have re-done it if they weren't happy with it, and they didn't, so not sure what's up with that.

I would have preferred it if he just kept the 5-count gimmick personally. It worked really well and this association with Ziggler an AJ, i know it hasn't been long but i do not see it helping him. No idea where it's going. I hope they prove me wrong though.
